The typical 25mm wide cargo strap I can buy locally is rated at 800 lbs or so, and the windup sheet metal in the ratchets will fail before the strap unless its around something sharp. At 1600 lbs, I'd have to tap the hold down holes and screw some bolts in to lift it 5mm's while other lifting means was rigged just to get it hooked to the jacking frame. Or set the jacks low and wire weld the frame to its base skirt. Knowing you, you got that puppy for the scrap iron price. I should be so lucky. How old is it?
